if these guys will shove with nothing on the board, reading them correctly and knowing you're ahead ain't gonna stop them sucking out on you a tiny proportion of the time while you rake in the cash the rest of the time

Fixed your post

I've frequently had my top 2 pair cracked by bottom pair landing a set on the river and as the example above shows, if these guys will shove with nothing on the board, reading them correctly and knowing you're ahead ain't gonna stop them sucking out on you.

There's a common misreading of the game in evidence here. When you play decent players who only play good or potentially good hands, you will still get sucked out on (an AK4 board where you have 44 and he has AK will suck out on you just as often as 469 where you have 44 and he has 96, but you wouldn't criticise him for playing AK) but you will also be beaten more often by genuinely good hands.

It's a hopeless task, fretting about terrible players sucking out on you, and focusing on these players. Don't focus on them, except to ensure you play aggressive, proper poker against them. I know it seems like donks are doing this shit all the time, and in freerolls, it'll certainly happen a loit more; but you will find that the great majority - especially when you play fees with buyins - don't do this. It's simply not worth fretting over when there are any number of other things about your game you can be working on and improving.
